APPARATUS FOR IMPREGNATING WOOD.

' Application filed lfovember 20, 1908. Serial No. 463,648.

To all whom it may concern:

Be it, known that I, WILLIAM W. NORMAN,

a citizen of the United States, residing at Hunterville, Missouri, have invented a new and useful Apparatus for impregnating Wood, of which the following is a Specification.

This invention has reference to an apparatus for impregnating wood with chemical or coloring matter, and particularly to an parts of the wood in such relation that both slabs or boards, as well as veneer surfaces cut from around the bodies of wood, will contain aseries of multicolor strips which harmonize with each other, thereby enhanc ing the pleasing appearance of the finished product.

I am aware that bodiesof wood have been rendered multicolor by having the coloring matter forced therein in concentric circles with thecenters or axes of the bodies of wood as the centers of the circles. An apparatus for treating the wood in this way is described in the patent to Willner, No. 807,411, dated December 12, 1905, p

I am also aware that bodies of wood have been rendered multicolor by forcing a single coloring matter into radial channels in the end of the wood and thence through the grain of the wood, then'changing the position of the wood body being treated and forcing another coloring matter into other radial channels, and then repeating the operation until the strips of coloring fill the entire body of wood, or so much thereof as it is desired to color. An apparatus for coloring the wood in this way is described in the patent to Willner, No. 771,689, dated October 4, 1904.

It will be observed that my improved ap-,

paratus and the wood treated thereby differ essentially from the above, all of which will clearly appear from the following description, referencebeing made to the accom- P y g drawings in which i through the wood. Fig. 2 is an elevation Figure 1 is a longitudinal sectional view of the apparatus and a body of wood engaged therewith and showing the stripes of coloring matter which have been forced illustrating the face of the gripping-head which engages the wood, and showing the chambers thereon from which the different colors are injected into the wood. Fig. 3 is an elevation of the supporting-head showing the channels or passages which conduct the coloring fluids to the proper chambers. Fig. 4 is an end or cross sectional view of a body of wood which has been subjected to treatment by my improved coloringapparatus, showing that all the colors extend inwardly from the surface of the wood.

This'device comprises a gripping-head adapted to have interlocking connection with the end of a body of wood to be treated and having its engaging surface divided into a number of compartments into which the coloring fluidsare to be forced, and from which said substances are forced into the fibers and thereby forming a water tight joint or connection with the wood. A multiplicity of flanges or ridges 3 are formed on the face of the gripping-head and have their outer ends in integral connection with the inclosing flange 2. These flanges or ridges divide the face of the gripping-head into a plurality of separate chambers or compartments, arranged preferably in series, .those of each series being designated by like reference characters. The chambers are so arranged that the layers of veneer cut from around the body of wood are cut transversely of the layers of color thus formed, which is also true of boards or layers of ve neer quarter sawed from the body and such parts will contain longitudinal strips of all the colors contained in the wood. A

The supporting-head 7 is attached to a shaft 8, Said supporting-head is provided with a series of concentric annular flanges 9 which form a series of annular passages 10. The rear'side of the gripping-head has an annular flange 11 which encircles the outer flange 9. A series of grooves are formed in outer annular passage designated by 5 holes the rear face of the gripping-head and the flanges 9 extend into said grooves, making tight joints with suitable sections of packing 12 in said grooves. A. series of screw-bolts 13 extend through holes in the supportinghead and screw into internally-threaded holes in the gripping-head, thereby rigidly fastening and holding said parts together. From that series of compartments designated by land 4 holes 14 open into the between the parts 1 and 7, constituting passages for admission of the coloring fluid into said series of chambers.

15 open into the next annular passage 10, admitting similar coloring matter'into each of said chambers 5. From the series of chambers 6 holes 16 open into another annular-passage 10, thereby admitting the same kind of coloring matter to all the chambers in this series. It will be observed that if fluids of different colors be in the different passages 10 such different colors will also be in the different series of chambers. Pipes 17 opening into the annular passages 1O constitute passages for the admission of the fluids and the pressure whereby said fluids are forced into the wood.

In operation the flanges 2 and 3 are engaged in the end of the wood, in the manner shown in Fig. 1. The fluids, whether of coloring matter or other material for' the impregnation of' wood, are admitted into the annular passages 10, and thence into the chamu :rs on the face of the gripping-head, the sing e outer annular passage 10 supplying one kind of coloring matter into that series of chambers indicated by 4 and l, while the middle annular passage supplies coloring matter of one color to all the chambers designated by 5, and thB'IIBXt annular passage admits coloring matter of onecolor to and thereby .-and through all the chambers to which the .reference character 6 is applied. Pressure, such as maybe obtained from steam or compressed air, as then admitted through the pipes 17 the fluids will be forced into the wood longitudinally with the grain thereof. In this way the 'wood may be made of variegated colors which will 1 be intersected'or-cut across when the layers of veneer are cut I wood or boards or veneer are quarter sawed matter has been from around the body of from the body, all of which will be readily understood by referring to Fig. 4' which shows a body of forced thereinto. It will thus be seen that. the layers of colorv ex tend transversely across the rings of owth and for this reason the contiguous e ges of 4 the adjacent layers of color will flow into each other and eambine more readily .by following the grain or rings of growth.

I am aware that there ma from the construction 'desc'ri ed and shown From that series of chambers wood after the coloring be variations without departing from the spirit and scope of the invention. 1 do not restrict myself to identical features, but

\Vhat I claim and desire to secure by Letters Patent is 7O 1. An apparatus for impregnating bodies of wood for veneer purposes comprising a gripping-head having an annular flange on the outer edge thereof, and flanges extending from the annular flange for forming chambers, which chambers extend from the annular flange inwardly toward the center of the gripping-head, some of said chambers receiving one kind of a coloring fluid, and others, other coloring fluids, said chambers so placed that the layers of veneer cut from around the bodies of wood contain a series of multi-colored strips, and means for introducing different colored fluids into the chambers for impregnating the wood with the different coloring fluids at one operation. 2. An apparatus for impregnating bodies of wood for veneer purposes comprising a gripping-head having an annular flange on the outer edge thereof, V-shaped flanges extending from the annular flange inwardly toward the center for forming fluid chambers therebetween, said chambers having passages for the introduction'of coloringfluids therein, some of the chambers receiving one coloring fluid, and others receiving other coloring fluids, said chambers so placed that the layers of veneer cut from around the bodies of wood contain a series of multi-colored strips, and means for mtroducing the different coloring fluids into the various chambers, whereby the woodwill be impregnated with the coloring fluids simultaneously.

3. An apparatus for impregnating wood comprising .a gripping-head having an annular flange on the outer edge thereof. flanges extending inwardly toward the center from the annular flange for forming fluid chambers between the inwardly extending flanges, said chambers having passages leading thereto for the introduction of the fluids, some of the chambers receiving one kind. of a coloring fluid and the other chambers receiving other coloring fluids, a supporting head connected to the grippinghead, concentric flanges formed on the supporting head engaging the gripping-head for forming chambers for the various coloring fluids therebetween, said last-named chambers in communication with the chambers on the gripping-head, and means for introducing the various coloring fluids to the concentriochambers whereby the wood to be treated will be impregnated with the various coloring fluids simultaneously.

4. An apparatus for impregnating bodies of wood for veneer purposes comprising a gripping-head adapted to engage an end of the wood being treated, a plurality of chambers formed on the gripping-head extending from the outer edge of the head so that the coloring fluid will extend from the outer edge of the object being treated toward the center thereof and layers of veneer cut from around the bodies of Wood are cut transversely of the layers of color thus formed, someof said chambers receiving one kind of a coloring fluid, and other chambers receiving other coloring fluids, and means for introducing various coloring fluids into the chambers of the gripping-head for impregnating the Wood simultaneously with a variety of coloring fluids.

5. An apparatus for impregnating wood comprising a head having grooves radiating t'rom the center, and grooves parallel ther with on one side of the head, and concentric grooves on the opposite side in communication with the radial grooves.
